Specification of Letters Patent.

Patented J une 9, 1914.

Application led September 24, 1913. Serial No. 791,535.

To all lwhom it may concern:

Be it known that we, GEORGE SrMAR'rIN and, MAX BERGER, citizens of theUnited States, residing at Anderson, in the county of Madison and Stateof Indiana, have invented certain new and useful Improvements inBrushes, of which the following is a specification.

The brush which is the subject matter-of the present application forpatent is de- -signed more particularly to be used for cleaning the typeof typewriters, letter presses, or other writing and printing machines,as well as printers forms, and its object is to provide a brush by whichthe cleaning of the type can be done easily and thoroughly, without lossof time and with a considerable saving of labor. This object is attainedby means of a novel combination and arrangement of parts to behereinafter described and claimed, reference being had to theaccompanying drawing, in which- Figure 1 is aside elevation of thebrush; Fig. 2 is a longitudinal section on the line 2-2 of Fig. 1, andFig. 3 is a cross-section on the line 3-3 ofl Fig. l.

Referring specificall to the drawing, 5 denotes the head of a rushhaving bristles 6 and 7, respectively, on opposite sides, a double brush.thus being had. The head has a central longitudinal passage 8 extendingthereinto from the rear end of the head and terminating short of theforward end thereof. From one side of this passage minute orifices 9lead through the head to that side thereof carrying the bristles 6 and4open through said side. A cleansing fluid, such as gasolene is adaptedto be discharged through the orifices onto the bristles 6, this part ofthe brush therefore forming a fountain brush,

The device is provided with a hollow, cylindrical handle 10 carrying atits outer end a cap 11 which is screwed on and is thus readily removablefrom the handle. .The cap has an externally screw-threaded nipple 12which is screwed into the outer end of the passage `8, whereby aseparable connection between the cap and the brush head 5 is der 16 inthe cap and across-pin 17 on the valve stem. a

The handle 10 carries a rod 18 for operatlng the valve 13. This rodextends centrally and lengthwise through the handle, from the butt endof which `it rejects and is fit ted thereat with a push utton 19. In thehollow of the handle 10 is a s ider 20 which supports the forward end othe rod, and between this spider and a cross-pin 21 on the rod, a spring22 is coiled around the latter, which serves to normally hold the rodretracted. The rod is in line with the valve stem 14, and when pushedforward it pushes against the inner end of the valve stem and unseatsthe valve 13. The rod is operated, to 'open the valve, by pressing onthe button 19, andy upon removing the pressure the spring 22 retractsthe rod and allows the spring 15 to close the valve.

The handle 10 is hollow in order that it may serve as a container forthe gasolene or other cleansin fluid, the same being discharged onto t ebristles 6 when the valve 13 is opened, the fluid thereupon discharginginto the 'passage 8 and `flowing through the orifices 9 to the bristles6.

The rear or butt end of the handle 10 is closed by a plug 23 having acentral air port 2.4, through which the rod 18 passes. The rod carries avalve 25 which seats over the air port when the rod is in retractedposition, to prevent leakage of the cleansing fluid from the butt end ofthe handle. When the rod is pushed in to open the valve 13, the valve 25is unseated and air is allowed to enter the hollow of the handlecontaining thesupply of cleansing fluid, and the latter is freelydischarged. The cap 11 is removable from the handle 10, as hereinbeforedescribed, in order to permit the latter to be filled with the cleansingfluid.

In use, the fountain brush formed by the bristles 6 is first employed toremove all accumulations on the type, after which the type is brushedwith the bristles 7, which latter remain dry. By this operation, thetype can be quickly and thoroughly cleaned. The removal of the cap 11does not disturb the valve 13 as the valve stem 14 and the rod 18 areseparate.

We claim:

A brush comprising a head carrying bristles and having a passage leadingfrom one end of the head, with orifices leading from the passage to thebristles, a hollow end of the handle, and to the aforesaid pas'- the airport When the rod is advanced to sage, a Valve carried by the cap andhaving open the first-mentioned valve.
